You can easily disable Bixby button in Galaxy S9 and S9+ if you frequently pressed the button inadvertently, or if you do not want to use Bixby.
This Galaxy S9 guide explains the functions of Bixby button in Galaxy S9 and S9+, and shows you how to disable Bixby button in Galaxy S9 and S9+.
Since Galaxy S8 (and S8+), Samsung added a dedicated button for Bixby with the hope of boosting the usage of Samsung’s AI assistant.
As shown in Galaxy S9 and S9+ layout, Bixby button is located on the left side of the phone below the volume keys.
- If you press the Bixby button on Galaxy S9 or S9+, the phone will open Bixby Home.
- If you long press (press and hold) the Bixby button, the phone will open Bixby Voice.
Samsung does not allow you to map the Bixby button on Galaxy S9 and S9+ to any other apps. It can only be used for Samsung Bixby unless you root the phone and mess up a few system settings.
Although Samsung Bixby has been dramatically improved since the initial release with Galaxy S8, in many aspects, it is still not comparable to Google Assistant, which can be enabled in Galaxy S9 or S9 by long tapping (tap and hold) the Home button. Some Galaxy S9 and S9+ owners may not want to use Samsung’s Bixby at all. They are happy with Google Assistant.
Some other owners may do not use either Google Assistant or Bixby. But they may press the Bixby button accidentally when they want to press the volume button or the power button.
Even some Bixby users may not want to use the Bixby Home, which comes out when you press the Bixby button. You can use other Bixby features without the button.
So, there are sizeable Galaxy S9 and S9+ owners who may want to disable Bixby button in Galaxy S9 and S9+. A few may even want to disable or uninstall Bixby from Galaxy S9 or S9+.
As Bixby is deeply integrated into Galaxy S9 and S9+, it is hard to uninstall or disable Bixby entirely without breaking some core features and functions of the phone.
But it is easy to disable Bixby button in Galaxy S9 and S9+.
Please note, Samsung does not allow you to map the Bixby button in Galaxy S9 or S9+ to other apps or functions. Samsung simply blocked this feature.
So, you have two options for the Galaxy S9 Bixby button: use it or disable it.
As mentioned earlier, there are two gestures for the Bixby button in Galaxy S9 and S9+: press for Bixby Home and long press for Bixby Voice.
You need to disable these two Bixby button gestures separately because they are independent of each other.
There are two methods to disable the press gesture for Bixby button.
Step 1: Access Bixby Home
You can access Bixby Home by pressing the Bixby button.
Alternatively, you can access Bixby Home in the leftmost panel of the Galaxy S9 Home screen if you haven’t disabled it as explained in this guide.
Step 2: Tap the settings icon on Bixby Home page
As shown in the screenshot below, tap the Settings icon (marked as 1).
Tapping the setting icon would expand the top part of the Bixby Home page.
Step 3: Switch off Bixby key
As shown above, you can find the switch for Bixby key in the expanded top part of Bixby Home page.
You can tap the switch to disable Bixby button for Bixby Home.
For example, as shown below, after you disable Bixby key, Galaxy S9 or S9 will not do anything if you press the Bixby button.
Please note, only the press gesture of the Bixby button was disabled. If you press and hold (long press) the button, you will get Bixby voice.
This method is the fastest way to disable Bixby button for Bixby Home.
Most Galaxy S9 and S9+ owners disable Bixby button for Bixby Home after removing the Bixby Home panel from Galaxy S9 Home screen.
On the Bixby Home page, tap the menu key (3 vertical dots) on the top right (marked as 2) to access the Bixby menu.
As shown above, in the Bixby menu, tap Settings (marked as 3).
In the Bixby Settings page as shown below, scroll down to find the Bixby key under the General section.
Tap the Bixby key as shown below.
As shown above, you can find there are two options for Bixby button (press gesture only):
- open Bixby Home.
- Don’t open anything (i.e., do nothing).
If you want to disable Bixby button in Galaxy s9 and S9+, you may tap Don’t open anything as shown above.
You can find the message below the options:
Pressing and holding the Bixby key will always open Bixby Voice.
This message reminds you that you can only disable the press gesture here so that Galaxy S9 or S9+ will not open anything if you press the Bixby button. But if you press and hold (long press) the Bixby button, you will still get Bixby Voice.
So, you need to disable the long press gesture somewhere else (read on).
On the Bixby settings page, you can swipe down and find the Voice section.
In the Voice section, as shown below, you can turn on or off Bixby Voice using the switch.
For example, as shown above, if you disable Bixby Voice, Galaxy S9 or S9 will do nothing when you press and hold the Bixby button.
But this switch will disable Bixby Voice entirely in Galaxy S9 or S9+. In other words, if you turn off Bixby Voice here, there will be no way to launch Bixby Voice on your phone. You essentially disable Bixby Voice on the phone.
But other Bixby features, e.g., Bixby Vision, will not be affected.
There are no other ways to disable Bixby button with the long-press gesture without disabling Bixby Voice.
After you disabled Bixby button as explained above, and removed Bixby Home from Galaxy S9 Home screen, you may suddenly want to try Bixby Home or use Bixby Voice.
In this case, you cannot access Bixby settings directly.
You need to re-enable Bixby Home in the Galaxy S9 Home screen as explained in this guide.
Once you can access Bixby Home, you will be able to access Bixby Settings.
In Android Pie update for Galaxy S9 and S9+, Samsung updated Bixby as well.
In the new Bixby, you cannot disable Bixby button anymore. You cannot turn off the Bixby button and cannot set the action as Do anything when Bixby key is pressed.
Furthermore, the long press gesture cannot be disabled as well.
But you can remap single press or double press of the Bixby button to any third-party apps or any Bixby quick commands, as explained in this guide.
To create and use Bixby quick commands, you may check this guide.
For other features (e.g., the night mode, navigation gestures, new Recents screen, floating keyboard, lift to wake, lockdown mode, rotation toggle, and the new camera app) and guides of Android Pie update for Galaxy S9 and S9+, you may check this page.
